Question

我使用毕加索库为我的应用程序，它到目前为止工作得非常好。我有一个图像视图，它可以在卡片布局中从网页下载图像。我希望当用户点击图片时，它会将该图像设置为墙纸。（我在这个PLZ中的一个菜鸟帮助了我，这是我打入的最后一件事。）

MainActivity.java

 class CustomViewHolder extends RecyclerView.ViewHolder{

RibbonLayout ribbonLayout;
ImageView imageView;

public CustomViewHolder(View itemView) {
    super(itemView);

    ribbonLayout = (RibbonLayout)itemView.findViewById(R.id.ribbonLayout);
    imageView = (ImageView)itemView.findViewById(R.id.imageView);

}
 }

自定义视图持有者

 public class CustomAdapter extends  RecyclerView.Adapter<CustomViewHolder>{

Context context;
List<Item> itemList;

public CustomAdapter(Context context, List<Item> itemList) {
    this.context = context;
    this.itemList = itemList;
}

@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(context).inflate(R.layout.item_layout, parent, false);
    return new CustomViewHolder(itemView);

}

@Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
    Item item = itemList.get(position);
    if (item.type == 0) { //new
        holder.ribbonLayout.setShowBottom(true);
        holder.ribbonLayout.setShowBottom(true);

        holder.ribbonLayout.setHeaderRibbonColor(Color.parseColor("white"));
        holder.ribbonLayout.setHeaderTextColor(Color.parseColor("white"));


        Picasso.with(context).load(item.imageURL)
                .into(holder.imageView);
    } else
        if (item.type == 1) { //hot
        holder.ribbonLayout.setShowBottom(false);
        holder.ribbonLayout.setShowBottom(false);
            holder.ribbonLayout.setHeaderRibbonColor(Color.parseColor("white"));
            holder.ribbonLayout.setHeaderTextColor(Color.parseColor("white"));




        Picasso.with(context).load(item.imageURL)
                .into(holder.imageView);
    }
    else
        if (item.type == 2) { //hot
            holder.ribbonLayout.setShowBottom(false);
            holder.ribbonLayout.setShowBottom(false);


            Picasso.with(context).load(item.imageURL).into(holder.imageView);

        }

}




@Override
public int getItemCount() {
    return itemList.size();
}

CustomAdapter

protected override byte[] GenerateCode(string inputFileContent)
        {
            try
            {
                var result=Engine.Razor.RunCompile(inputFileContent,DateTime.Now.Ticks.ToString());
                return System.Text.Encoding.UTF8.GetBytes(result);
            }
            catch (Exception e)
            {
                this.GeneratorError(4, e.ToString(), 1, 1);
                //Returning null signifies that generation has failed
                return null;
            }
        }

}

Answer 1

您可以使用毕加索的结果设置壁纸。

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36'}
r = requests.get(urldet, headers=headers)
soup = BeautifulSoup(r.content, "lxml")

Answer 2

在onClickListener上设置ImageView，从ImageView获取可绘制内容，并将其设置为壁纸

holder.imageView.setOnClickListener(new OnClickListener() {
      @Override
      public void onClick(View view) {
        try {
          Bitmap bitmap = ((BitmapDrawable)((ImageView)view).getDrawable()).getBitmap();
          WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);
          wallpaperManager.setBitmap(bitmap);
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    });

确保将壁纸权限添加到清单和运行时

<uses-permission android:name="android.permission.SET_WALLPAPER"/>

将imageView的内容设置为壁纸（毕加索）
